An Unexpected Halloween Surprise

Severus Snape did not expect his life to change so abruptly and dramatically on that rainy Halloween night, but those whose lives change as such rarely do. No, what Severus had been expecting was a lonely, boring evening pretending not to be home so delusional people dressed in ridiculous costumes wouldn't come up to Spinner's End (which they never did). He had just finished dinner and was settling into his battered armchair with a book in one hand and a glass of wine in the other when the knock came, the fated knock that irreversibly twisted his life so out of proportions that it could scarcely be called Snape's.

KNOCK KNOCK KNOCK

"I thought those damn muggles knew to leave me alone," he growled under his breath as he put his book and wine down on the sad-looking coffee table.

Severus swept dramatically up to his doorway and wrenched it open, fully prepared to give the poor muggles a piece of his mind they wouldn't forget. But the scalding words died in his throat as he gazed on a wet, shivering Lily Evans (no, Potter) plus a small boy on his doorstep.

"Lily?" He gasped.

"H-hi, Severus," she said miserably.

Severus gaped at his formed childhood friend in a very un-Severus like way.

"Can I come in?" Lily asked hopefully.

"Of-of course!" Severus said, recovering his ability to speak and moved aside so the soggy duo could step into his house. He closed the door after them and quickly muttered a spell to remove the water from the floor. "Can I get you anything? What are you doing here? Are you ok? Are you cold?"

Lily grinned in a way that made Severus's heart pinch but there was sadness in her smile. "One question at a time, Sev! I am a bit cold… and wet… and shivering…"

"Right." Severus summoned two towels from his linen closet and put on two cups of tea. He handed a towel and a cup of tea to Lily who accepted both gratefully and the same to the unnamed boy. Now that they were taken care of to a passable extent, he prepared for more serious questioning.

"Please don't take this the wrong way, but why are you here?" Severus gently asked the woman sitting on his couch.

Lily made a face and sipped her tea before answering. "Please don't take this the wrong way, but I really don't want to talk about that yet."

"Aah. I see. That's fine," Severus said, his head spinning. Only one person could make her upset like that and they both knew him well.

Potter, you jackass, what have you done now? He thought.

"I came to you because you were the only person I could think of," Lily said abruptly. Severus raised an eyebrow. "Well, you know! Tuney and I haven't spoken since I left school and I don't think I can face my other friends right now."

"That's fine," Snape assured her. "I'm assuming you need to spend the night?"

"That would be amazing," she admitted sheepishly.

"I'll go prepare a room," Severus said while rising.

"Wait!" Lily caught his arm. "Thank you. I know we haven't been friends since that day but you still accepted us into your home without question. I honestly don't know what I'd do without you, Sev," she confessed.

Severus smiled warmly, transforming his imposing, pinched and unhealthy face to a gentle, happy and attractive visage. "Of course, Lily! What are friends for?" He stood and walked to his only spare bedroom.

Inside, Severus Snape was cheering and rejoicing for all he was worth. His (former) best friend and love of his life had reappeared on his doorstep after a feud with his sworn enemy, asking to stay the night and openly addressing him as a friend! He practically danced around preparing a room for his beloved Lily and that boy-

Wait. The boy. Who was he?

Severus frowned. He was probably her son, which made him his son too. But with Lily as his mother, he couldn't be too insufferable, right?

"Your room is set up and the bathroom's down the hall if you want to shower," Snape announced as he returned to his living room. Lily looked up while the boy stared at his feet.

"Thank you, Sev. If you don't mind, I'm going to go shower?" Lily asked.

"There are towels in the bathroom but you have to hit the showerhead a few times before it'll work properly," he informed her. She grinned a normal, happy Lily smile and left the room.

Severus sighed dreamily and turned around, only to stop dead to face the boy. He was now looking straight into Severus's eyes with a determined expression on his face.

"Erm…" Severus wasn't good with children. At all. Ever.

"You're Severus Snape," the boy informed him. "Mummy and Dad talk about you a lot. Dad isn't very nice about you."

"Like I didn't already know that," Severus mumbled. "What's your name?" He asked louder.

"I'm Harry. Mummy likes you. You two are friends," he stated firmly.

"I suppose we are," Severus said tentatively. He wasn't quite sure where he was with Lily Evans but he didn't was to break the little he had by going too fast (Merlin, he felt like a teenager again!).

"No. You two are friends," Harry said resolutely.

"Alright," Snape agreed.

"Good!" Harry smiled, then snuggled up to Snape on the couch. "Good night, Uncle Severus."

For the second time that night, Severus Snape was at a total loss.

Lily came back into the room after finishing her shower, saw Harry, saw Severus, saw the expression on Severus's face (confused), and laughed. "I'll put him to bed now. Harry's a bit… forward… isn't he?"

"You could say that," Severus confessed. "You could also say blunt. Or tactless."

Lily laughed again. "I guess so. Goodnight, Severus." She walked away carrying her sleeping toddler.

"Goodnight, Lily," Snape mumbled. He sighed and picked up his glass of wine again.

What the hell had just happened?

A/N: Harry is young here, like 3 or so. Basically the youngest someone can talk coherently. (I have never raised a child so I don't know the youngest they can speak, so please don't hate me if the age doesn't match up!) Also, if any of the characters are OOC, please let me know! I'd love to hear your thoughts on how to improve my story ^.^
